How do the Fan Capacitor work?
The most common motor used in a normal household electric fan is a single-phase induction motor. When first switched on such a motor needs to use a “starter” winding, in addition to its main winding, so that a rotating magnetic field is created to make the motor’s rotor start to turn.

However a starter winding cannot do the job on its own, it needs a “Start-And-Run Capacitor” in series with the starter winding to create a rotating magnetic field. Without one of those capacitors the motor would never start to turn. Most ceiling fans use a type of motor known as a “permanent split capacitor motor“. These motors have two coils, a “start” and a “run” winding. A capacitor is connected in series with the start winding to insert a phase shift, but once the motor is up to speed it becomes an auxiliary winding. In order to reverse the motor, the Fan Capacitor is applied to the “run” winding which then becomes the “start” winding. In some cases the windings may have taps to provide different speeds, in others the value of the start/run capacitor is lowered to provide lower speeds. Yet other designs will have additional capacitors wired in series with the motor as a whole to regulate speeds.

Feature & Application

1. CBB61 Fan Capacitor small case, small dissipation factor, small inheterent temperature rise
